Nidec Corp. quality control and leadership crisis

Overview

Japanese motor manufacturer Nidec Corp. has disclosed extensive quality control misconduct spanning approximately a decade. An internal investigation revealed 844 instances of wrongdoing dating back to 2012, including faked product tests, unauthorized changes to manufacturing processes and materials, and false labeling of product origins.

Company leadership attributed the misconduct to employees working under intense pressure to meet targets during rapid expansion. While the investigation was initially prompted by suspected accounting fraud at an overseas group company, Nidec stated that no safety issues have been identified and no massive recalls are currently planned.

In response, President Mitsuyoshi Kishida has committed to fundamental reforms to prioritize quality and customer needs over internal logic, aiming to address deep-seated organizational culture issues. However, the company continues to face scrutiny as new irregularities emerge following the initial review of management systems.

As of late September 2026, Nidec is facing severe financial and leadership instability. Following reports that the board of directors resolved to dismiss President Kishida during an extraordinary meeting on September 25, Nidec shares plunged over 17% on the Tokyo Stock Exchange. The potential dismissal is reportedly linked to accounting irregularities and a massive anticipated impairment loss for the fiscal year ending March 2026.

While Nidec previously estimated the impairment at 250 billion yen, new reports indicate the figure may reach 1 trillion yen, significantly higher than a subsequent 400 billion yen estimate. In an official statement, the company confirmed it is “evaluating executive leadership changes and a large-scale impairment process,” though it maintained that no final decisions have been officially made at this time.
